ROD CUTTER.

Application filed September 2%). 1921. Serial No. 501,898.

To all whom it mayfconcem:

Be it known that l, VrNonNT BARTON, a citizen of the United States. residing atPort Angeles, in the county of Glallam and State,

of Washington, have invented certain new and useful Improvements in Rod Cutters,

of which the following is a specification.

This invention relates to rod cutters or shears.

The object of the invention is to provide a cutter of this character so constructed that it will quickly sever rods of various sizes and cross sectional shapesand which is simple, durable and compact, as well as inexpensive to manufacture and convenient and efiicient in use.

- Another object is to provide a device of this character, the movable blade oi which is spring returned to i acilit-atethe rapid feeding and cutting of a rod into sections.

Another object is to provide means constructed to prevent the movable blade from being expelled by its springs and ye'tnot interfere with its rapid operation. 1

Still another object is to equip a device oi? this character with a gage for regulating the length of the rod section to be cut so that pieces of uniform length may be quickly severed without necessitating any change after the gage is once set.

With these and other objects in view, the invention consists in certain novel features of construction as hereinafter shown described and claimed.

in the accompanying drawings:

Figure 1 represents a side elevation oi a cutter constructed in accordance with this invention. with the parts in position as shown ready for the insertion oi the square rod to be cut. i

Fig. 2 is a plan view thereoi with the rod to be cut shown in dotted line.

Fig. 3 is a transverse verticalsection.

Fin". 4L is a detail perspective view of the movable cutter blade.

-Fig. 5 is a plan view with the movable cutter blade removed and with parts broken out for convenience in illustration. 1

Fig. 6 is a front elevation with 1 arts broken out and in section of: the movable cutter blade constructed for use in sever- The cutter shown in Figs. 1 to 5 is designed for use in cutting rods, polygonal in cross SQC'tIOH. while Figs. 6 and 7 show cooperatingblades for use in cutting cylin drical rods, the main or body portion oi the cutter in connection with which these blades are used is the same, and various sets or pairs of cutters may be provided, the several pairs 1 being readily interchangeable as will behereinai'ter more fully described.

. in theembodiment illustrated the body 1 ot the cutter is shown rectangular in configuration and is provided in its upper ends with a socket 2, in which is designed to be mounted and to reciprocate the movable cutter blade 10, the socket 2 opening through the bottom of the body 1, as shown at Thebotto n i of the body 1 is slotted longi tudinal throughout its entire length, as

shown at '5, to form a seat for the fixed cutter blade 15 which is here shown of less thickness than the movable blade 10 and is equipped with a rod receiving notch 16 formed in its inner edge and is designed to cooperate with a similar notch 11 formed in the inner edge of blade 10. The fixed blade 15 is inserted in the seat 5, formed in the bottom oi:' the body 1, and is secured in position bybolts 18, passing transversely througirthe body 1 and through the opening 17 near the ends of the blade 15, as. is shown clearly in Figs. 1 and 2.

The bottom of the socket 2 on opposite sides of the recess 6, forins'housings or chainbers for coiled springs 14 and are equipped with studs 15. which operate as retainers to hold the springs lat againstlateral movement. The lower ends otthe springs 1 are engaged'with the studs 15, as is shown clearly in Fig.1 and their other ends are housed in sockets 13, formed in the lower face of bladelO near the opposite ends thereof. as is shown clearlyat 13 in Fig. 2 and at 13 in Fig; 6.

The movable blade .10 is provided. on one face with a peripheral groove .12, which opens through the top of the blade and terminates at its lower or inner end, at a point adjacent the top of the notch 11 of said blade, as is shown clearly in Fig. i. This groove 12 is designed to receive the inner end of a bolt 10 which is threaded through one sidewall of they body 1 above the recess v V-shaped inform so that when in normal position a rectangular openlng wlll be formed between the-inner end oi the blade to receive a square rod R to be cut.

, ends with apertures 17 for the passage therethrough or the securing bolts 18.

A bore 19 extends transversely through the body 1 near one end thereof, as is shown clearly in Fig. 2, being designed.- to receive the shank 21 of a gage 20, here shown L-shaped in form, the short arm 22 thereof being flattened and adaptedto be swung into alinement with the opening in the body through which the rod R to be cut is clesigned to be inserted. I

The shank 21 of the gage 20 is preferably threaded and is held in adjusted position by a lock nut 23, so that the arm 22 which forms a stop adapted to engage the end of the rod to be cut may be positioned toward or away from the body 1 according to the length of the rod section or rod to be cut and when adjusted is locked by the nuts 23, so that the rod to be out may be rapidly fed through the cutter and be severed by a blow on the upper or outer edge of the blade 10.

From the above description it will be obvious that when the blade 10 is inserted in the body 1 that the bolt 10 is screwed into position, shown in Fig. 3, where its inner end or point enters the groove 12 a sufficient distance to cause it to engage the lower end of said groove when the blade is projected to its extreme outermost position, and prevent the blade trom being expelled beyond the proper pointby the springs 14, and yet the bolt is not suiiiciently tight to bind on the blade and interfere with its rapid reciprocation.

In use the nuts 23 having been loosened, the parts being in the position shown in Figs. 1 and 3, the rod R to be cut is inserted transversely through the opening formed in the body 1 between the notched cutting edges 11 and 16 of the blades 10 and 15 and projected through the recess 6, according to the length of sections desired to be out. When projected a suiiicient distance the gage 20 is swung into the position shown in Fig. 2 with the arm 22 engaging the outer end of rod and when so positioned the lock nuts 23 are tightened and the gage securely held. It is of course understood, as is shown clearly in Fig. 3 that the blade 10 overlaps seated within the complementing notches 11 any suitable means, not shown.

movable cutter.

and 16 of the blades, so thatthe cutting edges will entirely embrace said rod. Then by striking the upper edge of blade 10 with sufiicient force, the cutter is driven downwardly so as to sever the rod, it of course beingunderstood that any suitable means may be employed for forcing the blade 10 downwardly into cutting engagement with the rod. lmmediately'the rod is severed the springs'la will operate to quickly return blade 10 in position again ready for use, and the rod It may be fedthrough the body of the cutter until its outer end again abuts the stop 22 of the gage 20 and the operation above describedis repeated.

If desired, additional locking means for the gage may be provided in the form of a bolt 24, shown in Fig. 2, which extends through one end or" the body 1 into the bore 19, through which the rod passes.

The body 1 may be secured in position by To change the cutting blades all that is necessary is to loosen the bolt 10 and remove bolts 18 and then substitute the cutterslO and 15 shown in Fig. 6 or any others having cutting notches. shaped to conform to the configuration of the rods to be severed.

After these blades are inserted bolts 18 are restored and secured and the bolt 10? therein tightened up, as above describedand the cutter willbereadyfor use in connection with a rod conforming in cross sectional contour to the shape of the notches carried 1.
